The drop in SMP PPD is due to the new 2.10 a2 core that Stanford released a few days ago to deal with the bad workunits going around. So on the one hand, we don't have to babysit our clients to take care of any bad units that hang them up, but on the other hand, there's about a 30-40% drop in PPD with this new core compared to the older 2.07/2.08 versions.

I have an 8800GT here that is being a complete bitch. It wants to fold at 300 PPD for some reason. Priorities/affinity isn't an issue. The card hasn't dropped into a power saving mode - all clocks on the gpu are normal. A similar card in another machine on the same unit is getting 5000 PPD.
